PEA OR BEAN SHELLING MACHINE.

SPECIFICATION forming part of Letters Patent N o. 727,339, dated May 5, 1903.

Application led February 26, 1901. Serial No. 48,978. (No model.)

T0 cti/Z whom t may concern:

Be it known that we, EPHRAIM J. FOSTER and JAMES M. FOSTER, citizens of the United States, residing at Steubenville, in the county of Jefferson, and in the State ot Ohio, have invented a new and useful Pea or Bean Shelling Machine, of wh ich the following is a specification.

Our invention relates to pea and bean shelling machines; and the object of the same is to produce a device of this character for removing partially-ripened peas and beans from the yet green pods without crushing them.

The simple and novel construction designed by us for carrying out our invention is fully described in this specification and claims, and illustrated in the accompanying drawings, forming a part thereof, in which- Figure l is a front elevation of our device clamped to a support, shown in fragment. Fig. 2 is a side elevation of the same without the support. Fig. 3 is a section on the line 3 4, Fig. 2. Fig. 4. is a section on the line l 2, Fig. l, and showing a pea-pod between the rolls. Fig. 5 is a detail of the feeding-rolls. Fig. 6 is a section on the line 5 6, Fig. 3. Fig. 7 is a section on the line 7 8, Fig. 3. Fig. S is a plan View of our device with the casing open.

Like characters of reference designate like parts in the dierent views of the drawings.

The letter A designates a casing which is formed in two sections connected by hinges l and secured by latches 2. The casingA is substantially cylindrical and has heads 3. A bench-clamp B serves to secure lthe device to a support and is connected to the casing by a shank 4, formed integral therewith.

A hopper O is formed integral with the casing A and serves to receive the pods to be shelled. Mounted within the casing and located in alinement with the hopper O is a pair of feed-rollers D D', which bear reduced spindles 5, journaled in bearings in the heads 3. The roller D is traversed by a transverse V- shaped groove 6, while the roller D has a transverse groove 7 therein, rounded out on the arc of a circle. Mounted inthe circular groove 7 and located just opposite the vertex of the V-shaped groove 6 is a circular slittingknife I), designed to slit lthe pods longitudinally as they pass between the feeding-rolls. Gears G and F are mounted on two of the spindles 5 and are located to mesh to drive the knife-bearing roll D'. The feed-roll D is driven by means of a crank M, which serves to operate the machine.

From the feed-rolls the slitted pods pass into the embrace of a pair of squeezing-rolls E E, bearing spindles 8, journaled inthe casing A. The squeezing-rolls are located lin contact and are roughened to adapt them to grip the pods.

Two U-shaped springs N, having arms 9 and l0, are mounted within the casing A at opposite ends of the rollers. One arm, 9, of each of the springs is curved at 92l and bears on the roll E', while the other arm, l0, is held by lugs 1l and bears on the roll D. By this arrangement of the spring N the squeezingrolls E E are yieldingly-held in contact.

In order to drive the roll E', a gear L is keyed on one of its spindles 8 and is located to mesh a gear K, carried by the feeding-roll D. A pair of gears I-I and J are keyed on the spindles 8 of the rolls E and E', respectively, and are arranged to mesh to communicate the movement of the roll E to the roll E.

As an outlet for the pods an aperture l1 is formed in the casing A adjacent to iianges 12. A spout is also formed on the casing A and serves as an outlet for the shelled peas.

ln operation the crank M is turned by hand, and green pods are introduced endwise one at a time into the hopper O. The sloping sides of the groove 6 will deflect the pod into Vthe vertex of the groove, where it will be engaged by the circular knife b and slitted longitudinally, after which the slitted pod will pass to the squeezing-rolls E E', which feed it along rapidly and eject the peas through the slit, when they will fall into the spout P. The empty pod will continue through the rolls E E and drop out at 41l.

We do not wish to be limited as to details of construction, as these may bemodied in many particulars without departing from the spirit of our invention.

Having described our invention, `what we claim as new, and desire to secure by Letters Patent, is-

l. In a pea and bean sheller, the combination of a feed-roll having a V-shaped groove ICO therein, a feed-roll having a circular groove therein, and a circular knife carried by said last-mentioned roll, and located in said oireular groove, whereby the pods passing between said rolls are slitted by said knife Without having the peas therein crushed, and means for driving said rolls, substantially as described.

2. In a pea and bean Sheller, the combination with feed-rolls, of squeezing-rolls and U shaped springs mounted to yieldingly hold said squeezing-rolls in Contact, substantially as described.

3. The combination of a casing formed with outer and inner portions, and with suitable bearings for shafts, a pair of rolls formed with corresponding peripheral grooves, one

of said rolls being provided with a peripheral slitting-knife mounted centrally of its groove, a second pair of rolls elastieally held together and having surfaces roughened or otherwise adapted to exert traction upon the pods, and gearing for transmitting the required motion to the several rolls, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing Witnesses.
